Isolate Resistors Before Measurement
To measure resistance, select the ohms mode, remove the resistor to be measured from your circuit, and place the ohmmeter leads across the resistor leads. It is not OK to use your fingers to do this
Notes
- The Ohmmeter works by placing a small voltage across the circuit element. The current that flows through the element in response to that voltage determines the ohmmeter reading.
- You cannot measure the resistance of a resistor while it is in a circuit - there may be many other current paths available, or the battery may force current backwards through the ohmmeter.
- Some ohmmeters require "zeroing." Just touch the probes together and make the appropriate adjustment.
